実験手順

A solution of 1H-benzo[c][1,2]thiazine 2,2-dioxide (0.381 g, 2.1 mmol) and 10% palladium on carbon (0.05 g) in anhydrous methanol (6 mL) was placed under a hydrogen filled balloon and stirred at room temperature for 17 hours. The mixture was filtered through Celite and concentrated to give a white solid (0.366 g, 95%). 1H NMR (CDCl3, 300 MHz) δ 7.25-7.16 (m, 2H), 7.07-7.01 (m, 1H), 6.76-6.73 (d, 1H, J=8.4 Hz), 3.51-3.46 (t, 2H, J=6.8 Hz), 3.34-3.29 (br t, 1H, J=6.9 Hz).
